Análisis de la app Grease Gun Run para 19 de enero

Fill the grease tubes as much as possible and collect the grease. Use greases to clean dirty pistons. The more you clean the dirty pistons, the faster your pistons will work and the faster your car will go. Be careful not to keep the pistons dirty, it's the pistons that make your car go fast. Don't forget to clean the gears on the doors and open the doors.
